If your watch is a Rolex and you purchased it brand-new, then it should still be under its 5-year factory warranty and you can bring it back to Rolex for regulation and adjustment. Modern Rolex watches should adhere to timekeeping tolerances of -2/+2 seconds per day, so if yours is losing a minute every two weeks then it would be running outside of specs.
For non-Rolex watches, COSC-chronometer tolerances permit -4/+6 seconds of timekeeping variance per day, so assuming your watch is running on the low end of that range (-4 seconds per day), losing about a minute every two weeks is close to its manufacturer specifications (total loss over 14 days = 56 seconds).
